15 Claims. (ci. 24a- 159) This invention relates to a wound yarn package and method of winding.

One object of the invention is to produce an improved package having a self-sustaining crosswound end or ends but largely wound in a spool wound formation, thus attaining nearly the high density and high capacity of a cylindrical spool wound package but wound on a core from which one orboth of the heads are omitted.

Further objects of invention are to improve the construction of aheadless cross-wound end portion of a wound package. In particular the invention aims to avoid cob-webbing or failure of the cusps of yarn to lie in the desired plane at the end face and to avoid excessive iianging or unduly large diameters of the end portions as compared with the main portion of the package.

These aspects of the invention are of especial importance in winding on ring spinning or twisting machines or similar machines where the traverse element is at some distance from the face of the winding package so that a sharp reversal of the yarn at the end face is ordinarily impossible, and where there is no provision for applying pressure to the package to roll or press its end portions in to the desired diameters.

Other objects of invention and features of advantage and utility will be apparent from this specification and its drawing wherein the invention is explained by way of example.

In the drawing:

Fig. 1 is a side view of the tubular core with a layer of quick traverse winding thereon;

Fig. 2 is a side view of the same tubular core with a few, for example, twenty layers of quick' winding on the tubular core a few layers of cross winding (for example twenty) as shown in Fig. 1. This cross winding will, after a few layers have been laid, pile up at the ends of the package and there form flanges 8, 8 where the cusps of the` spirals of yarn overlie.

Then a few layers of winding having a slower traverse than the initial layersrof cross winding, preferably asA shown in Fig. 3 consisting of spool winding, that is slow traverse winding having the coilsV nearly perpendicular to the axis of the package, are laid on the package.` This slow traverse or spool winding has a slightly shorter vlaid on the package and further similar flanges are built up at the ends of the package, and then the slow traverse winding is again resumed, having aslightly shorter length of traverse than the cross winding, and this slow traverse or spool Winding isagain continued until the diameter of the package is as large in the center as it is at the ends. This sequence is preferably continued until the package reaches its desired diameter, which may for example be such as indicated in dotted lines in Fig.y 3. n

The invention permits the winding, on a machine that has no provisionrfor rolling in the flanges that form at 'the end faces of the package, of an outwardly cylindrical package which is tied together endwise by cross winding and hence is self-sustaining, and which has a greater yarn`\ capacity due-A to its being wound in large part a plurality of layers of cross-winding:i and in a plurality of layers of winding having a slower traverse than the said layers of cross-winding, and adding further pluralities of layers of crosswinding and pluralities of layers of winding having a slower traverse than the cross-winding, said layers of cross winding and layers of slow traverse winding being superposed.

2. A method of preparing a textile package comprising winding the Same yarn alternately in a plurality of layers of cross-Windingv and in a plurality of layers of spool winding, and adding further pluralities of layers of cross-winding and pluralities of layers of spool Winding until the package is completed, said layers of cross winding and layers of spool winding being superposed.

3. A method of preparing a textile package comprising winding the same yarn alternately vin a plurality of layers of cross-winding in which flanges are built up at the ends of the package, andina plurality of layers of winding having a slower traverse than the cross-winding in the space between said flanges, and adding further pluralities of layers of cross-Winding and pluralities of layers of winding having a slower traverse than the cross-winding until the package is completed.

4. A method of preparing a textile package length of traverse than the cross winding, and comprising winding the same yarn alternately in wound in layers of cross a plurality oi layers of cross winding in which flanges are built up at the ends of the package, and in a plurality of layers of spool winding in the space between said flanges, and adding further pluralities of layers of cross winding and pluralities of layers of spool winding until the package is completed. Y

5. A method of preparing a textile package comprising winding the same yarn alternately in a plurality of layers of cross winding, in which flanges are built up at the ends of the package, and in a plurality of layers of winding having a slower traverse than the cross winding in the space between said ilanges, and adding further pluralities of layers of cross winding and pluralities of layers of winding having a slower traverse than the cross winding until the package is completed, the slower traverse winding having a slightly shorter length of traverse than the cross winding.

9. A package consisting of the same yarn wound in layers of cross winding and in layers of winding having a slower traverse than the layers of cross winding, the slower traverse winding being interspersed between layers of cross winding and having a slightly shorter length of traverse than the cross winding.
